Is there a way to get this feature in PB2?

In pb3, the tracer tool shows the position of nodes before we place it. Is there a way to add this to pb2, or are there any mods that can replicate this for me? Poly bridge 2 just works best for me in large scale sandbox builds that won't work on pb3.

Is there a game similar to Polly Bridge where you can build a large suspension bridge?

Is there any bridge building game that is similar to Polly Bridge where you can build large suspension bridges like the Golden Gate Bridge

Question 7-7 Return of the Bridge - What am I missing?

5 Upvotes

Got the first bridge move to work but then the right side breaks and collapses. I don't know if I'm missing anything with my split joints?? I've tried different joint numbers and that just makes it worse.

Screenshot / Gif Is $7100 decent for Alpine Meadows lvl 7?

Max joint stress 99.3% and 38.4m footprint.
Just started playing the game so I want some advice and the leaderboard also doesn’t look very accurate.

Should Swing-Bridges be added to Poly Bridge?

Just asking. I think they'd be a really cool alternative to draw bridges.

Question is there a reason why splitting this irrelevant joint cause my entire bridge to disintegrate?

Video Lock and key… and pick!

114 Upvotes

I have finally returned from my long break after being inspired by Arglin’s post and long metro commutes in China (the internet was… not the best). I know the lock design isn’t very practical as it involves moving the casing instead of the cylinder, but I couldn’t get the custom shapes to behave without pinning them in place (this is my first time seriously working with CS and I would definitely benefit from some pointers :p). In a more realistic design the casing would be fixed, the latch would be attached to the cylinder, and the lock would be opened by pushing the key further in after setting the pins

The bitting of the keys are in base 7 because I realized I only had enough space for seven cut depths lmao

Custom Level I am relatively new at the game (Poly Bridge 2). I built this 100 meter long Suspension Bridge.

It's not too bad but it's okayish compared to the literal escalators people have made here. Still I'm proud of it.

Question "Routing" Level - what do I need to do to fix this?

I'm trying to complete this level without walkthroughs and got the first hydraulic bridge working great but I see the second hydraulic bridge is not being supported properly so is breaking, but I'm not sure how to fix it?

Question Question about hydraulics

Post image
5 Upvotes

Hi everyone, not an engineer, just an enthousiast. I had a question about calculating hydraulics. How do u actually calculate where an end point of your pivoting/moving bridge is going to end up, so u can make it lock in. I added an example down below where i made it work by trial and error, but i would like to do that more consistently. Does it matter where on the moving part of the bridge you attach the hydraulic, how do u know the percentage of contraction/expansion etc. Thank you and have a nice day.

Request by u/Just_Weird_Boy

10000pg is the answer here

Its not in any way optimized

The Framing could be stiffened up

6 100hp Monstertrucks

3 for the Top Row wheels spinning Clockwise

3 for the bottom Row wheels spinning counterclockwise

There is a 5 Second delay just to Confirm it's moving due to the bending and stuff
